Objective To improve the scientific literature novelty assessment by studying the characteristics and novelty of researches in clinical medicine.Methods The objects, levels, locations, methods and novelty of 380 scientific literature novelty assessment files in Library of Guilin Medical College from 2012 to 2014 were analyzed by chi-square test.Results The novelty of researches was mainly manifested as an effect index in 2012-2013 and as an in-tervention factor in 2014(x2=110.12, P<0.01).The novelty of effect index was mainly manifested as a compre-hensive index in 2012-2013 and as a sensitivity index in 2014(x2=44.10, P<0.01).Conclusion Understanding and keeping abreast of the characteristics and novelty of researches in clinical medicine can serve them better and more effectively encourage their innovation .

Objective To compare the differences between state-owned hospitals and private-funded hospitals in Shanghai on the introduction and application of hospital marketing conception. Methods Questionnaire and interviews were conducted to reflect understandings in marketing conception,advertisements,hospital brand,customers' sense of satisfaction,etc. Results State-owned hospitals were less concerned in marketing conception compared with their private counterparts,even less sufficient in marketing input or management. Conclusion The state-owned hospitals should update their conception and enhance their ability of marketing management.While the private hospitals need to maintain the moderation of marketing and deal with the relationship among marketing,profit and development properly.

Objective To reduce or prevent the incidence of bile duct injury in the laparoscopic cholecystectomy,and reduce the postoperative complications of Bile duct injury in the laparoscopic cholecystectomy by time and exact treatment during the surgical procedure.Methods We retrospectively analyzed the clinical data of 8700 cases of LC, including 12 cases of bile duct injury, from September 1991 to today. The corresponding treatment was used in LC to avoid bile duct injury, when bile duct injury occurred, the injury was recognized and immediately repaired by surgery. Result The mean follow-up period after surgery was 5-10 years,all 12 patients with bile duct injury were cured and discharged. Conclusions We should correctly handle the relationship of various duct and avoid burn or cut duct for reducing incidence of the extrahepatic bile duct injury. Correct treatment can reduce or avoid the incidence of postoperative complications.

Objective To investigate the changes of serum troponin I (cTnI) in children with severe pneumonia in the early time and its significance in the diagnosis of myocardial damage.Method cTnI was measured by automatic chemo-immuno-analyzer in 47 patients with severe pneumonia during acute stage and 25 patients during recovery stage.Results The levels cTnI in blood of 33 patients with severe pneumonia during the acute stage were obviously higher,with the abnormal rate 70.2%.There was a remarkable difference compared with control group(P

This study aims to investigate the relationship between odor and contents of the chemical compounds in Lonicera japonica, including chlorogenic acid, galuteolin and polyphenols. High performance liquid chromatography (HPLC) was applied to determine the contents of chlorogenic acid and galuteolin in L. japonica. The ponptent of polyphenols was determined by UV-Vis Spectrophotometry. Electronic nose was used to extract and measure the odor of L. japonica. Then SPSS 17.0 software was employed for data processing. There is a significant positive correlation between the comprehensive index value of aroma and the contents of chlorogenic acid and polyphenols. The regression equations have been established. However, the relationship between the comprehensive index value and the content of galuteolin is not obvious. This is proof that the odor of L. japonica has close connection with the chemical compounds. Therefore, this research offered a new method for initially determine or predict the content of the chemical composition in L. japonica,

Objective To construct the recombinant plasmid pYES6-S and express and purify spike protein of severe acute respiratory syndrome(SANS)coronavirus in Saccharomyces cerevisiae. Methods DNA fragments of SANS coronavirus were obtained by reverse transeription.Four over- lapped fragments of spike protein genes were amplified by polymerase chain reaction(PCR)and ligated into an integral spike protein gene by restriction enzyme digestion.The spike protein gene recombined with pYES6 and cloned into E.coll.The recombinant plasmid pYES6-S was induced and expressed in Saccharomyces cerevisiae(INVScl)by galactose.Results The recombinant plasmid pYES6-S was confirmed that inserted fragment was right in length,direction and base matching by restriction enzyme digestion and sequencing.The purified protein encoded by the whole spike protein gene was about Mr 110?10~3 identified by electrophoresis.Conclusion The whole spike protein gene of SARS coronavirus is cloned into E.coli and the protein is expressed in Saccharomyces cerevisiae successful ly.which can be helpful in SARS vaccine research.

The results of open-field test,step-through passive avoidance task and radial-arm maze experiment showed that changes of locomotor activity,anxiety-related behaviour and ability of learning and memory were associated with the increased apoptosis of neurons in hippocampus in rats with perinatal hypothyroidism.
